INTRODUCTION

Nagpur district is endowed with a variety of flora, which can be considered as the store house of Original Article protection chemicals like flavonoids, alkaloids, essential oil etc. Nowadays, there is a renewed interest in botanicals because of the adverse effects of chemical pesticides. Still, recently only the plants with toxic chemicals were considered as suitable for plant protection. The discovery of antifeedant, insect growth regulators and other behavior modifying chemicals in plants against insect pest, fit into the concept of insect pest management assume importance (F. Brisca, 2009).

However, synthetic insecticides have serious drawbacks such as pest resurgence and resistance, lethal effects on non-target organisms, the risk of users, contamination, food residues and environmental pollution (Tapondjou et al ., 2002). Biological control is the use of one or more types of beneficial organisms, usually called natural enemies, to reduce the numbers of another type of organism, the pest (Susan E. Rice Mahr et al ., 2001). In addition, the precautions necessary to work with traditional chemical insecticides (Fields et al ., 2001) and the poor storage facilities of a traditional farmers in developing countries, which are unsuitable for effective conventional chemical control (Tapondjou et al ., 2002) emphasize the necessity of new effective methods for insect pest control of crops.

As Asteraceae family is nested high in the angiosperm phylogeny Asterideae/. The family contains the largest number of described, accepted species, of any plant family, CA. 24,000, with estimates of the total number reaching 30,000. There are 1600-1700 genera distributed around the globe except for Antarctica. Assuming that there are 250,000-350,000 species of flowering plants, then out of every eight to twelve species is in Compositae (about 10%) (Vicki A. Funk et al . 2002). Asteraceae family having compounds like flavonoids, saponins, tannins, phenols, steroids, terpenoids, etc. In the present paper some common plants of Asteraceae family having biopesticide potential are discussed.

Plant Distribution: Common throughout along roadsides, waste places and forest edges.

It is an annual, branching herb which grows up to 1m in height. The stem and leaves are covered with fine white hairs, the leaves are ovate and up to 7.5cm long. The flowers are purple to white, less than 6mm across and arranged in a terminal inflorescence. The fruits are achenes and easily dispersed. Because of its propagation, it becomes a weed and causes problems for farmers and ecologists. Seeds are positively photoblastic, and viability is often lost within 12 months (Tailor Chandra Shekhar and Goyal Anju, 2012).

Aerial parts of Ageratum conizoides contained 11 chromenes, nine methoxyflavones (like 5,6,8,3’,4’,5’-hexamethoyflavone and 8-hydroxy-5,6,7,3’,4’,5’-hexamethoyflavone), sitosterol, (+)-sesamin and caryophyllene oxide. Other components of this plant are alkaloids, flavonoids, benzofurans and terpenoids. The plant shows insecticidal properties.

Ageratum conizoides has bioactive activity that may have agricultural use as shown by several research investigations, in different countries. Pereira in 1929, cited by Jaccoud (1961), reported use of the leaves as an insect (moth) repellent (Tailor Chandra Shekhar, 2012). The insecticide activity may be the most important biological activity of this species (Harborne, 2010). Both the essential oil and as well as the major components of the oil, namely the precocenes, have been reported to have antijuvenile hormonal activity (Shirwaikar A et al , 2003).

A. Coincides possesses hormone antagonist precocene I and II and Artemesia vulgaris contain a substance sesquiterpenoid location named as ‘Vaughan’ (Sharada Singh and Rao P.J., 1999).

Hexane crude extract of A. conizoides (Coumarin) shows insecticide activity (toxicity) to Sitophilous zeamais, Rhyzopertha dominica, Oryzaephilus surinamensis of stored products (Marcio Dionizio Moreira et al ., 2007).

The extracts of A. conyzoides shows the larvicidal and ovicidal activity of aqueous and ethanolic extracts of leaves on the eggs (unembryonated and embryonated), first and second larval stages of Heligmosomoides baker i (J. Wabo Pan et al ., 2011).

It is used to repel pests in stored grain as well as aphids, ants, beetle, cabbage root fly, caterpillars, crickets, mites and termites. Bidens biternata also have some active components like chalcones, aurone glycosides, volatile oils, acylated okanin glycoside, gallic and oxalic acid and phenolic astringents. Some of these, particularly the volatile oils, are considered responsible for the mosquito repellent (T. C. Kazembe and S. Nkomo, 2012).

Leaves of Bidens pilosa and soap powder were used as an insecticide for the control of leaf miners and other insects. Similarly, PAN (2008) indicated that B. pilosa was effective against aphid, cutworm and termites. Likely, in this study, B. pilosa was minimized the number of onion thrips population, but exhibited low mortality rate percentage (Tadele Shiberu and Amin Mahammed, 2014).

Flowers and Fruits: throughout the Year Compounds and Biopesticide Properties

Tridax procumbens contains alkaloids, carotenoids, flavonoids (catechins and flavones), fumaric acid, FL-sitosterol, saponins and tannins. It is richly endowed with carotenoids, saponins, oleanolic acid and ions like sodium, potassium and calcium. Luteolin, glucoluteolin, quercetin and isoquercetin have been reported from its flowers (Sneha mundada, 2010).

Tridax procumbens along with eighteen weeds were selected, and a pesticide was produced from them by extraction method. The produced biopesticide was tested in 5 agricultural fields against tea, paddy, maize and cabbage plants. The pesticide was highly effective against aphids, leaf folder disease, thrips, Japanese beetle, army worm and the cutworm caterpillar. The effect of the pesticide derived from the agricultural weeds was around 50 to 75% more than the conventional chemical based pesticide (Manish Krishna, 2013).

CONCLUSIONS

Knowledge of the toxic plants, their toxic principles and their biological activity is of paramount importance not only to enable them to be utilized as natural pest control agents and replace the commercial synthetic pesticides, but also to enable us to understand the nature of their toxicity to non-targeted animals. Over 2,000 plant species have been reported to possess pesticidal activity (Crosby, 1971; Chakraboraty and Basu, 1997) out of about 2,500,000 angiosperms so far documented, only a fraction of which have been analyzed.

In Asteraceae, variations are enormous in which each subgroup specializes in one or more characteristics. Since evolution is never ending, this group represents different lines on which the evolution progressed and would progress.

This family is the most diverse family and its each and every part having noble biopesticidal activity. The work done till today on its biopesticide activities like insecticidal activity (toxicity), larvicidal activity, nematocidal activity, fungicidal activity, acaricide. Various species act against aphids, leaf folder disease, thrips, Japanese beetle, etc.

In future, there is huge room for research in the direction of more pesticide activities of the Asteraceae family and to elucidate the mechanism of action of the same.
